REPORTS PASSENGER TRAFFIC INCREASE OF 5.7%

FOR AUGUST 2006

Guadalajara, Jalisco, Mexico, September 12, 2006 - Grupo Aeroportuario del Pacífico, S.A. de C.V. (NYSE:PAC; BMV:GAP) (“the Company” or “GAP”) today announced terminal passenger traffic figures for the month of August 2006 compared to traffic figures for August 2005.

During August 2006, total terminal passenger traffic increased 5.7% compared to the previous August, driven by domestic passenger traffic, which grew 8.0%.

The two main factors that continue to drive this growth are the following:

• the resumption of operations by Aerocalifornia, and

• the increased activity of low-cost carriers, or LCCs.

Compared to August 2005, domestic terminal passenger traffic registered a net increase of approximately 86,400 passengers, mainly driven by passenger traffic growth at the Aguascalientes, Bajío, Guadalajara, La Paz, Los Mochis, Puerto Vallarta, Los Cabos, Tijuana and Manzanillo airports. The airports with the most notable increases were Aguascalientes with approximately 500 passengers, Guadalajara with approximately 48,900 passengers, Bajío with approximately 6,300 passengers, Tijuana with approximately 27,900 passengers, Puerto Vallarta with approximately 5,500 passengers, Los Cabos with approximately 7,400 passengers, La Paz with approximately 3,900 passengers, Los Mochis with approximately 1,800 passengers and Manzanillo with approximately 900 passengers (representing a total increase in domestic passengers at these airports of approximately 103,100 in August 2006 as compared to August 2005). In the cases of Guadalajara, Bajío, Los Mochis, La Paz and Tijuana these increases continue to be largely attributable to the routes operated by such LCCs as Interjet, Volaris, Alma, Click and Avolar, and in the case of Los Cabos and Puerto Vallarta, these increases were due primarily to the increasing popularity of tourist destinations served by GAP’s airports.

In addition, several new routes were established to and from GAP’s airports in August 2006, including Hermosillo – Toluca (Volaris), Hermosillo – Monterrey (Volaris), Hermosillo – Tijuana (Volaris), Guadalajara – Chihuahua (Alma) and Tijuana – Chihuahua (Alma). It is not yet possible to determine the overall effects of these routes on GAP’s passenger traffic.

In the case of the La Paz and Los Mochis airports, the growth experienced in August ends a decline in passenger traffic at these that resulted from the suspension, beginning in April

2006, of the operations of Aerocalifornia. Aerocalifornia resumed limited operations during the second half of August 2006.

At the same time, GAP experienced declines in domestic terminal passenger traffic in the airports of Hermosillo, with a decrease of approximately 4,600 passengers, Morelia, with approximately 5,500 passengers, and Mexicali, with approximately 6,500 passengers, representing a total decrease of approximately 16,600 domestic terminal passengers in these three airports compared to August 2005.

In terms of international terminal passenger traffic, the most significant increases were observed in Puerto Vallarta (with approximately 7,900 passengers, an increase of 6.0% compared to the previous August), Los Cabos (with approximately 4,000 passengers, an increase of 2.5% compared to the previous August), Guadalajara (with approximately 3,600 passengers, an increase of 1.5% compared to the previous August), Aguascalientes (with approximately 3,400 passengers, an increase of 27.9% compared to the previous August) and Bajío (with approximately 2,200 passengers, an increase of 4.7% compared to the previous August).

The growth in international passenger traffic at the Guadalajara airport was mainly due to the addition of routes to and from Atlanta, Chicago, San Jose, Fresno and Ontario. In the cases of Puerto Vallarta and Los Cabos, these increases are in line with past results and continue to be driven mainly by U.S. and Canadian tourists.

Decreases in international terminal passenger traffic at the La Paz, Hermosillo and Manzanillo airports resulted from the suspension of operations of Aerocalifornia, which included its La Paz-Los Angeles, Hermosillo-Los Ángeles and Manzanillo-Los Ángeles routes. Despite the limited resumption of Aerocalifornia’s operations, these three routes remain without service.
